' WINDOW-SCREEN.

Specification of Letters Patent.

' tion, and inexpensive in cost of manufacture- The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings. l I

Referring briefly to the drawings, Figure 1 is a front elevational view of my device attached'to a window. K

Fig.2 is a cross-sectional view ofthe same taken substantially on the line 2-2 of Fig. 1. Fig. 3' is'a perspective view of a portion of the upper window frame, showing my means of attaching the screen to the window frame.

Fig. 4 is a cross-sectional view of the latiier taken substantially onthe line 42- 1 of 1g..3.

Fig. 5 is aperspective view of the end portion. of the screen which is attached to the window frame.

. Fig. 6 is an abridged cross-sectional View of one of the screen rollers, showing the spring therein. v

Referringlnow in detail to the drawings,

the numeral 1 represents. the window frame and.2 the window sashes slidable in said.

frame. A reel screen 8 is attached to the upper edge of said window, and its other end is rolled upon the drum20 concealed in the wall above the frame 1. A shaft 21 supports said dru'm,and in the usual manner a coiled spring 20 normally forces said drum in the direction to wind said screen thereon. The manner of attaching the screen to'the window is'as follows: Upon the edge of the screenis a ledge of metal 23 having project of the window and adapted to receive the ing edges 23. -Projectin'g from said ledge are spaced apart eyelet members 22. In the window frame to which the screen is to be attached is a groove 24 running the length said ledge. Recesses 15 are provided in said groove for the reception of said eyelet members 22. Horizontally out recesses 13 are ber slidably along the recess 13*".

out in the .front of said window frame to communicate with said recess 15. A good view of both these recesses is given in Fig. 4c. In the recess 13 is slidablymounted a T shapedmember 17 the stem portion thereof pro ect1ng forward out from said recess to provide a handle for moving saidT memrearof the latter is a compression spring 16 tending to normally hold said T member toward the sash-ward side of its recess.

member 22 sets into said Now the eyelet recess 15, the member 17 being meanwhile forced to the rear of the recess 13 and the said member 22 is pushed as far as it will go intothe recess'15. Then the handle portion" of the member 17 is released, and the free end of said member 17 is forced by the sprlng 16 into engagement with the member '22. through the eyelet in the latter. Thus the screen is securely attached to the window frame. w

It is apparent from Fig. 2 that the slot 25, in the window frame, is of slightly less In the width than the ledge 23, so that there is no danger of the latter being drawn into the frame; this precaution prevents any possibility of a portion of the open window from being unprotected by the screen, as will be apparent below. A handle 11 is provided for the hinged cover 4, hinged at 5, in order to open or close the same to expose the rolled screen within its compartment in the frame. A similar handle is shown at the lower p25- though-most of the above description has been applied to the upper window frame, the

same applies to the lower, as the construc- 1 tion is exactly the same,'the same type of screen being attached to the lower frame, and operating in the same manner.

I have provided an auxiliaryventilating attachment at 10, Fig. 1, which is adapted to be rotated about a pin 10 by means of a handle 9, a metal frame 8 supporting the tional to the amount of rotation, for ventilation, and flies and other insects are kept out by the perforated sector 8?, which is fixed in position.

\ From the description above and the drawings referred to, the advantages and manner of operation of the device are readily inferred. Assuming first that-thewindow is closed, that is, that the upper sash 2 is in its same in the window. On rotatlng this member 10 clockwise, a space is left free propo'r-' "uppermost position, and the lower sash 2 in frame so as to cover the open space thereby created,-thus excludin the entry of insects through thewindow. %imilarly if the upper frame 2 is lowered, the screen 7 will follow the frame. lhus, without any additional efi'ortor thought, the window is at all times screened when open, and there is also no clouding of the View through the window, when closed, as there is in the case of the common type of screen which always stands in the window sash. 7

Having thus described my invention, what I claim and desire to secure by Letters Patent is as follows:. x

1. A device of the class described comprising a window sash, agroove in the upper.

part thereof extending through the length of the sash, vertical recesses in said sash ex- I tending from said groove into said sash,

- tal recesses, the stem of said Text ending' horizontal recesses in the side of said sash communicating with said vertical recesses, T, shaped members slidable 1n sald horizonoutward from said recesses to provide a handle portion, a screen adapted to roll upon a drumconcealed in the window frame, a

ledge attached to the free end of said' screen, members spaced apart extending ward from said recess to provide a handle portion, resilient means in said horizontal recess attached to said T member, a screen adapted to roll upon a drum concealed'in the window frame, meanson the free end of said screen adapted to 'set in said groove, and

additional mean'sthereon adapted to enter said vertical recesses and to be engaged vby the said T members. n
